[0057] Furthermore, when the hot air mechanism 3 is in an idle state, the lifting drive cylinder 331 can drive the air supply assembly 31 to descend to a position close to the bottom plate 1, thereby preventing the air supply assembly 31 from interfering with the riveting mechanism 2.

When the air supply component 31 rises to its position, the second drive cylinder 3321 works to drive the air supply component 31 to move away from the riveting mechanism 2, so that the hot air guide block 34 moves outward from the top of the lower riveting fixture 22, thereby resetting the air supply component 31 to the area of ​​the hot air mechanism 3, realizing the independent separation of the riveting mechanism 2 and the hot air mechanism 3, and avoiding the movement interference between the air supply component 31 and the riveting mechanism 2 during the movement process based on the cooperation between the lifting drive cylinder 331 and the second drive cylinder 3321.
